The details come more than a month after GM disclosed it plans to launch at least 20 new all-electric and hydrogen fuel cell vehicles globally by 2023. Pictured is the Chevy Bolt EV.

General Motors expects its electrified vehicle business to be profitable with the launch of its next-generation EV platform in 2021, CEO Mary Barra says.

Automakers have been losing money for years on all-electric vehicles such as the Chevrolet Bolt in exchange for meeting tighter environmental regulations while positioning themselves for an expected increase in demand for alternative powertrains.

Barra said GM expects the second-generation EV platform, which could underpin vehicles that exceed 300 miles in range, will drive total per-unit cost down 30 percent or more. That includes lowering the cost of battery cells to less than $100 per kilowatt-hour from $145 per kWh for the Bolt EV.

“We are working to provide desirable, obtainable and profitable vehicles that deliver a range of over 300 miles,” Barra told investors Wednesday at the Barclays 2017 Global Automotive Conference in New York. “There’s a lot of really creative things we’re doing to achieve that profitability point for that new platform.”

Barra said the all-new modular EV platform will be used across several market segments and GM brands. To help reduce costs and increase flexibility of the platform, she said the company is integrating the battery cells into the architecture.

At least two of the four vehicles planned by 2020 are expected to be small crossovers. Barra said GM will have an “all-new small CUV segment” with two entries and presence in two global markets -- presumably North America and China. She added that those vehicles will feature innovative technologies such as its Super Cruise autonomous highway driving system.

“We are really heading into the sweet spot of where the retail market is and is heading,” she said.

In the presentation, Barra said GM will eventually offer at least 11 kinds of vehicles off the new modular EV architecture, including a large SUV, a large luxury SUV and a "low roof car."

EV infrastructure

GM, according to Barra, is working on speeding the installation of DC fast chargers for EVs that nearly all customers will be able to use.

“We’re not big believers that we’re going to get to a zero-emission future by having unique charging systems and walling off our vehicles from other charging infrastructure,” she said, indirectly taking a shot at Tesla Inc.’s exclusive Supercharger stations. “Our focus is on the customer, so that means removing barriers for ownership.”

Barra provided no details about GM's plans to increase the availability of EV charging points, which is at more than 1,100 in the U.S., but said the company will “partner, incentivize or invest” to make it happen.

Connectivity

GM will also expand its connected vehicle services such as OnStar and soon launch a new in-vehicle feature called "marketplace" that allows users to "do things, to order things" more simply than with a smartphone.
